Abstract

Spectrum sensing is one of core technologies in cognitive radio. It can adapt to complicated electric-magnetic environments. By detecting environments in real time and extracting interference characteristic in frequency spectrum, it can use flexible spectrum assign strategy for adaptive communications. Spectrum sensing technology is discussed in this article. Then the realization scheme is proposed and applied in frequency-hopping communication systems. Computer simulations show that it can exactly provide spectrum occupation in real time for frequency-hopping communication systems.
